Detailed Solution

The product of (197 × 203) is 39991.
Given,
197 × 203.
We know that,

(x - y) (x + y) = x^{2} - y^{2} .

Converting 197×203 into the form of the identity,
Then,

197 \times 203 = (200 - 3) (200 + 3)

\Rightarrow (200^{2} - 3^{2})

\Rightarrow (40000 - 9)

\Rightarrow 39991

Hence, the product of 197×203=39991.
